Well, that’s because Roy Halladay once had a pretty terrible season himself.

Starting against the Tigers, Matusz gave up six runs in five innings on Sunday, just slightly increasing his ERA from 10.68 to 10.69. It’s the worst ERA ever for a pitcher who made at least 10 starts in a season.

Since Matusz, who averaged barely more than four innings an outing in his 12 starts, came up one-third of an inning short, Halladay still holds the record of highest ERA for anyone with at least 50 innings pitched in a season. Matusz is the new record holder for guys with 40+ innings. Stu Flythe of the 1936 Athletics holds the record at 30+. He had a 13.04 ERA in 39 1/3 innings.

I’m going to go out on a limb and say it’s more likely that Matusz follows in the footsteps of the other eight guys on that list. The guys who, for some weird reason, didn’t go from having ERAs in the nines to being the best pitcher in baseball.
